In the last day, I have received 6 private e-mails asking me what I do for cardio.

What is this sudden obsession with Cardio? Is it because I'm teaching Isometrics?

Answer:

12" Step-Ups X 12 minutes while wearing a 32-pound weight vest. (Much tougher than it sounds). This exercise was Dr. Laurence Morehouse's #1 cardio exercise. But it also has a leg strengthening component to it quite a bit like lunges.

or 300 Hindu Squats in 12 minutes. Naturally, one can do much more but the question is WHY? Believe me, 300 Hindu squats performed full range is more than enough for cardio.
